Vitamin D—often called the "sunshine vitamin"—is essential for many aspects of health, from maintaining strong bones to supporting the immune system. Produced in the skin in response to sunlight, it can also be found in foods like eggs, oily fish, and fortified cereals. In Ireland, however, limited sun exposure often leads to Vitamin D deficiency, making supplementation vital for many.
Why is Vitamin D Important?
Vitamin D is crucial for several key functions:
- Bone Health: Vitamin D aids in calcium absorption, helping to keep bones and teeth strong.
- Immune Support: It plays a critical role in maintaining a healthy immune system, helping the body fight off infections and illnesses.
- Muscle Function: It contributes to normal muscle function, supporting mobility and reducing the risk of muscle-related issues.
Vitamin D Deficiency in Ireland
Due to Ireland’s latitude, many people don’t get enough natural sunlight to maintain adequate Vitamin D levels, especially in winter. A 2013 national survey found that:
- 35.7% of adults aged 50-64 and 44% of adults aged 65-84 had insufficient Vitamin D levels.
- These deficiency rates increased to 55.4% and 48.1%, respectively, during winter.
The issue has likely worsened as people spend more time indoors due to lockdowns and social distancing.
Vitamin D and COVID-19
Research has suggested that Vitamin D may influence the body’s response to COVID-19. Vitamin D is believed to reduce levels of CD26, an adhesive molecule the virus uses to enter cells. Additionally, Vitamin D can potentially moderate inflammatory responses—specifically IFN-y and IL-6—which are linked to severe COVID-19 outcomes in critically ill patients. While more research is needed, maintaining adequate Vitamin D levels is important for general immune support.
Recommended Vitamin D Intake
In response to high deficiency rates, the Irish Department of Health recommends:
- Adults over 65: 15mcg (600 IU) of Vitamin D daily.
- Children under 12 months: 5mcg daily from birth, as advised by the Department of Health for Children.
- Children aged 1-4 years: 5mcg daily from Halloween to St. Patrick’s Day to counteract reduced sunlight exposure.
Vitamin D for Pregnant Women
Research has shown that Vitamin D deficiency during pregnancy may increase the risk of preeclampsia. Supplementing Vitamin D during pregnancy can support both maternal health and fetal development.
The Takeaway: Why Supplementing Vitamin D is Essential
Due to limited sunlight in Ireland, Vitamin D deficiency is common, impacting immune health, bone density, and overall well-being. A daily Vitamin D supplement can support immune resilience, maintain bone health, and contribute to healthy muscle function.
